MySQL 5.6 for REHL 6.4編譯安裝
MySQL安裝方式有多種，可以使用rpm包二進制安裝，也可以使用源碼進行編譯安裝。很顯然，編譯安裝的好處很多，就是能夠對將要使用的MySQL數據庫進行定制，
對于特定的操作系統、特定的應用、特定的MySQL功能要求很適合。因此，這里記錄一次MySQL 5.6 for REHL 6.4編譯安裝過程。
1、操作系統信息檢查并卸載操作系統自帶的過低版本Mysql
[root@arbiter ~]# uname -a
Linux arbiter 2.6.32-358.el6.x86_64 #1 SMP Tue Jan 29 11:47:41 EST 2013 x86_64 x86_64 x86_64 GNU/Linux
[root@arbiter ~]# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 6.4 (Santiago)
[root@arbiter ~]#
[root@arbiter ~]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
#::1 localhost6.localdomain6 localhost6
192.168.144.111 arbiter
[root@arbiter ~]#
[root@arbiter cmake-2.8.10.2]# rpm -qa|grep mysql
mysql-libs-5.1.66-2.el6_3.x86_64
[root@arbiter cmake-2.8.10.2]# rpm -e --nodeps mysql-libs
[root@arbiter cmake-2.8.10.2]# rpm -qa|grep mysql
[root@arbiter cmake-2.8.10.2]#
2、檢查MySQL編譯安裝必須的操作系統依賴包
rpm -q --qf '%{NAME}-%{VERSION}-%{RELEASE} (%{ARCH})\n' make \
gcc-c++ \
libstdc++-devel \
ncurses-devel
[root@arbiter ~]# rpm -q --qf '%{NAME}-%{VERSION}-%{RELEASE} (%{ARCH})\n' make \
> gcc-c++ \
> libstdc++-devel \
> ncurses-devel
make-3.81-20.el6 (x86_64)
package gcc-c++ is not installed
package libstdc++-devel is not installed
package ncurses-devel is not installed
[root@arbiter ~]#
3、安裝MySQL編譯安裝必須的操作系統依賴包
--掛載系統鏡像配置本地的yum源
[root@arbiter ~]# mount /dev/cdrom /mnt
mount: block device /dev/sr0 is write-protected, mounting read-only
[root@arbiter yum.repos.d]# cat local.repo
[local]
name = local
baseurl=file:///mnt/
enabled = 1
gpgcheck = 0
gpgkey =file://mnt/RPM-GPG-KEY-CentOS-6
[root@arbiter yum.repos.d]#
[root@arbiter yum.repos.d]# yum clean all
Loaded plugins: product-id, refresh-packagekit, security, subscription-manager

Cleaning repos: InstallMedia base extras local updates
Cleaning up Everything
[root@arbiter yum.repos.d]#
--使用yum安裝操作系統缺少的rpm包
yum -y install gcc-c++
ncurses-devel ncurses-devel
4、上傳、解壓并安裝cmake
[root@arbiter ~]# ls
anaconda-ks.cfg cmake-2.8.10.2.tar Documents install.log Music pkg rpms test
Desktop Downloads install.log.syslog Pictures Public Templates Videos
[root@arbiter ~]# tar -xvf cmake-2.8.10.2.tar

5、創建mysql用戶
groupadd -g 20000 mysql
useradd -u 20000 -g mysql mysql
[root@arbiter ~]# groupadd -g 20000 mysql
[root@arbiter ~]# useradd -u 20000 -g mysql mysql
6、創建mysql安裝目錄并授權
mkdir -p /application/mysql-5.6
mkdir -p /application/mysql-5.6/data
mkdir -p /application/mysql-5.6/log
mkdir
-p /application/mysql-5.6/tmp
chown -R mysql:mysql /application/
chown -R mysql:mysql /application/mysql-5.6/tmp/
chown -R mysql:mysql /application/mysql-5.6/log/
chmod 775 /application/mysql-5.6/log/
chmod 1771 /application/mysql-5.6/tmp/
chown -R 775 /application/
chmod 1777 /tmp
7、上傳解壓MySQL并編譯安裝
[root@arbiter ~]# ls
anaconda-ks.cfg cmake-2.8.10.2.tar Documents install.log Music Pictures Public Templates Videos
cmake-2.8.10.2 Desktop Downloads install.log.syslog mysql-5.6.36.tar.gz pkg rpms test

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system
PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
/application/mysql/bin/mysqladmin -u root password 'new-password'
/application/mysql/bin/mysqladmin -u root -h arbiter password 'new-password'
Alternatively you can run:
/application/mysql/bin/mysql_secure_installation
which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.
See the manual for more instructions.
You can start the MySQL daemon with:
cd . ; /application/mysql/bin/mysqld_safe &
You can test the MySQL daemon with mysql-test-run.pl
cd mysql-test ; perl mysql-test-run.pl
Please report any problems at http://bugs.mysql.com/
The latest information about MySQL is available on the web at
http://www.mysql.com
Support MySQL by buying support/licenses at http://shop.mysql.com
New default config file was created as /application/mysql/my.cnf and
will be used by default by the server when you start it.
You may edit this file to change server settings
WARNING: Default config file /etc/my.cnf exists on the system
This file will be read by default by the MySQL server
If you do not want to use this, either remove it, or use the
--defaults-file argument to mysqld_safe when starting the server

2017-07-27 01:06:19 28474 [ERROR] Do you already have another mysqld server running on socket: /application/mysql-5.6/tmp/mysql.sock ?
2017-07-27 01:06:19 28474 [ERROR] Aborting
原因是：my.cnf配置中mysql.sock文件存放目錄或權限有問題
解決方法：檢查socket配置的路徑是否存在，socket指定的路徑下mysql用戶是否有讀寫權限
mkdir -p /application/mysql-5.6/tmp
chown -R mysql:mysql /application/mysql-5.6/tmp/
chmod 1771 /application/mysql-5.6/tmp/
啟動異常二、日志相關
[root@arbiter ]# /etc/init.d/mysqld start
Starting MySQL.170727 00:56:52 mysqld_safe error: log-error set to '/application/mysql-5.6/log/mysqld.log', however file don't exists. Create writable for user 'mysql'.
ERROR! The server quit without updating PID file (/application/mysql-5.6/data/arbiter.pid).
[root@arbiter ]#
原因是：my.cnf配置的log目錄不存在或mysql用戶對其沒有讀寫權限
解決方法：檢查相關路徑是否存在并創建授權
mkdir -p /application/mysql-5.6/log
chown -R mysql:mysql /application/mysql-5.6/log/
chmod 775 /application/mysql-5.6/log/
